FELT ROLLER.

SPECIFICATION forming part of Letters Patent NO. 472,899, dated April12,1892. l Application filed September 12, 1891. Serial No. 405,529. (Nomodel.)

To a/ZZ whom, it may concern:

Be it known that I, JOHN W. MILLET,a citizen of the- United States,residing at Dolgeville, in the countyof Herkimer and State of New York,have invented new and useful Improvements in Felt Rollers, of which thefollowing is a specification.

This invention relates to an improvement in felt rollers; and the objectof the invention is to obtain a seamless felt roller, as set forth inthe following specification and claims, and illustrated in the annexeddrawings, in which- Figure l is a longitudinal section of the rolleralong Fig. 2. Fig.v2 is a section along y y, Fig. l. Fig. 3 is a detailView of the felt cover. Fig. 4 is a section along z z, Fig. 3. Fig. 5 isa detail view of the base or core. Fig. 6 is' an end View of Fig. 5.Fig. 7 is a detail view of a Wedge. Fig. S is an end view of Fig. 7.Fig. 9 is a face View of a head or end for the roller. Fig. 10 is asection along w w, Fig. 9. Fig. ll is an enlarged end View of the Wedgein place.

The felt tube or coveringA is made unbroken or in form of aseamless-hollow cylinder, said covering being made of any desiredconsistency. The base or core B is hollow and is made of any suitableresilient material. I prefer brass for the material of the core B;

but of course other substances-such, for example, as steel, Celluloid,hard rubber; and the like-might be made to answer the,pur pose.

The core or base B has a out or opening for the insertion of a Wedge orexpander O. When the wedge is withdrawn, the core B can be compressed,so that the covering A is readily slipped upon said core. When the coveris in place, the Wedge C is forced into place, whereby the core B isexpanded and the cover A is stretched, so as to sit tight and smooth onthe core.

The wedge or expander and the edge of the cut or opening in core B havesuitable tongues D and grooves E, so that the wedge is accurately guidedduring its insertion and held in place when inserted.

The heads F, of brass or other suitable material, are secured to theends of the roller. These heads have suitable eyes for the passage ofscrews or bolts G, extending through the interior of the roller from onehead to the other to secure said heads in place.

Vhen the wedge C is introduced in the longitudinal cut or opening of thecore B, the outer surface of such Wedge constitutes a continuation ofthe outer surface of the core, so that the continuity of the surfaceofthe core is substantially unbroken and the felt covering is supportedat all points.

The-felt roller is particularly designed for use in printing-presses,and is specially useful for printing Wall-paper.

What I claim as new, and desire to secure by Letters Patent, is

l. A seamless felt roller consisting of a metallic or resilient hollowbase or core and an unbroken felt cylinder or cover, said .core having acut or opening and a wedge or expander for said opening, said Wedgebeing made to rest in said opening, With its outer face in continuitywith the surface of the core, substantially as described.

2. A seamless felt roller consisting of a Inetallic or resilient hollowbase or core and an unbroken felt cylinderorcover, said core having aout or opening and a wedge or expander for said Opening, said Wedge orexpander and the edge of said cut or opening being suitably tongued andgrooved for supporting the Wedge, With its Outer face in continuity withthe surface of the core, substantially as described.

In testimony whereof I have hereunto set 85 my hand in the presence oftwo subscribing Witnesses.

JOI-IN W'. MILLET.
